What « Doctors Reveal »: The 4 Crucial Cautions
1. The Oxalate Content: Kidney Stone Risk
-
Fact: Cashews are moderately high in oxalates. For individuals prone to calcium-oxalate kidney stones, high intake can increase risk.
-
Advice: If you have a history of stones, enjoy in moderation (≤1 oz/day) and ensure high calcium intake (calcium binds oxalates in the gut).
2. The Raw Cashew Myth & Toxicity
-
Critical Fact: « Raw » cashews sold in stores are not truly raw. They have been steamed to remove urushiol, the same toxic resin found in poison ivy.
-
Never consume truly raw cashews straight from the tree—they can cause severe allergic dermatitis and are toxic.
-
Advice: Only purchase from reputable sources. Home-processing is dangerous.
3. The FODMAP Factor for IBS
-
Cashews contain galacto-oligosaccharides (GOS), a FODMAP carbohydrate that can trigger bloating, gas, and pain in those with Irritable Bowel Syndrome (IBS).
-
Advice: Those with IBS should follow a low-FODMAP diet initially, then test tolerance. A 10-15 nut serving is typically considered low-FODMAP.
4. Calorie Density & Portion Distortion
-
The biggest practical risk is mindless overconsumption. Eating straight from a large bag can lead to a 400-500 calorie snack easily.
-
Advice: Always pre-portion. 1 ounce (≈18-20 nuts) is a standard serving. Use a small bowl, not the bag.
